If location is everything, this is great! Tony and his family / staff have fast communication, and are located so very close to the BTS station (and walkable from Phaya Thai Air Rail Link station) as well as the water taxi pier by Jim Thompson's house (to make travel to the Golden Mount area or the Market area (other direction) so convenient. The major malls / Erewan Shrine and even university are also just a little bit further by walking or 1-2 stops on the BTS.
You will appreciate the individual air conditioning units in each room as well. (My unit's remote needed a few extra clicks to start it, but is a blessing with the 35 Celsius heat and humidity of Bangkok.) Bring light breathable clothes in any month. This is a walk-up (no elevator) building, so those with heavy bulky suitcases or mobility issues with stairs may not find it preferable. It is also a personal residence with shared spaces. There are two shared showers and toilets on one floor for the 4 room rentals. The rooms have TV, a robe, slippers, towel, and tastfully decorated. There are many available toiletries, with washcloths in the sink area for the showers. The nice added touch was a cooked breakfast, fresh fruits, and tea/coffee/water prepared for the guests. You are near a 7-11 (with ATMs) and many street food vendors and coffee shops, plus hotel restaurants nearby. The ride share app Grab is also available for transport in Bangkok. I was very pleased with the home hospitality and friendliness from Tony and his family, and would be eager to stay there again.
